OsmoPure
Rensselaer Polytechnic Institute, 2009 - $10,500
This E-Team is developing OsmoPure, a low-cost water purification device for developing countries based on simple membrane filtration technology. While there are a number of water filtration devices being marketed to the poor, many of them don’t work in murky water (they get easily clogged), often require a large energy input in order to work (e.g., hand pumping), and fail to remove all contaminants. OsmoPure is a compact, cartridge-based, multi-stage water purification system. To produce potable water, the user fills a plastic bottle with dirty water, screws on the purifier like you would screw on a cap and squeezes the bottle to dispense clean water. When the filter looks dirty, the user simply shakes the fluid inside to remove debris. The purifiers are meant for plastic bottles that exist currently as rubbish in the target areas, cutting production and distribution costs and creating an environmentally friendly solution to the global water crisis.
